FIELD OF THE DISCLOSURE

This disclosure relates generally to the field of air blower assemblies, and more specifically to a dual rotor system and apparatus for high output and the removal of contaminants from air.

BACKGROUND

Indoor air quality has increasingly become an important issue as public health knowledge has increased as well as demand for sterile environments. Particularly, many pathogens such as viruses, molds and bacteria are now known health risk. Further, in traditional fan assemblies these pathogens are known to multiply and be circulated.

There have been several attempts to solve the problems in the prior art to purify air in environments where clean air is desired. Some examples include air purifying devices that use ultraviolet light, such as UV-V or UV-C, to decontaminate air passing through a fan assembly. These devices often connect to home heating and air-condition systems to sterilize air being circulated in a home. Other examples have their own blower capabilities and often use an UV-V light emitting source, into a destratification fan, to catalyze an oxidation reaction inserted into a destratification fan.

However, traditional air purifying devices are often stationary and are capable of purifying the air on a predetermined area. The devices that are portable, or that can quickly be moved and installed, often are not capable of quickly purifying large volumes of air. Further these devices often sterilize air by catalyzing an oxidation reaction and not use a specific wavelength to the kill the pathogens.

Due to all of the existing shortcoming in presently available devices, there is still a need for an air purifying device having a large volume capability that is also easily transportable.

Ring-shaped assembly 349 may be configured to attach around the outer circumference of second electric motor 346. Ring-shaped assembly 349 may be made out of an aluminum alloy pipe having a 4″ diameter, 2½″ length and 0.38″ thickness with one or more UV-C LEDs 355 positioned on the outer surface of ring shaped assembly 349. The aluminum alloy pipe acts as a base to mount UV-C LEDs 355 on while dispersing the heat UV-C LEDs 355 generate. In other non-limiting embodiments ring-shaped assembly may be any size or made out of any material.

Ring-shaped assembly 349 sleeves onto the outside of second motor 346 of air purification assembly 100, allowing air to pass around and through the ring-shaped assembly 349, keeping UVC LEDs 355 at ambient room temp (typically 68-72 degrees Fahrenheit). In this embodiment, this ensures proper operation of UVC LEDs 355 due to the nature of it being inefficient in heat dissipation for large amounts of UVC power. When mounted on the ring-shaped assembly 349, UVC LEDs 355 may be positioned 2″ from interior surface of tubular shaped body 302. UVC LEDs 355 emit light between 265-275 nm (mutates the DNA of micro-organisms). These UVC LEDs 355 are maximally effective at a 2″ range. UVC LEDs 355 have a tendency to overheat and become less efficient. The air purification assembly 100 keeps them at room temperature and functioning at peak capacity.

UV-C LEDs 355 may communicate via control system 105 with a microprocessor or driver via a bus. Bus may communicate with microprocessor which controls UV-C LEDs 355 to turn off or on in specific increments of time so UV-C LEDs may last longer than if they were to run continuously. Microprocessor may also adjust output for maximum UV-C LEDs 355 power and maximum efficiency. Power is brought to ring-shaped assembly 349 from Driver in parallel and low voltage via copper inlays in second hub assembly 348 of the air purification assembly 100. The Positive (+) and Negative (−) leads from the microprocessor are connected to bus which is embedded in second hub assembly 348. UV-C LEDs 355 may be powered in series off of bus and may be in pre-arranged even numbered sets (2, 4, 6, etc.) for exact power to each individual UV-C LED 355. In some non-limiting embodiments UV-C LEDs 355 are 0.013-0.1 mW UVC spectrum (265-275 nm) LEDs, programmable driver 0-54V 0-1100 mW, and bus may be built into second hub assembly 348.

In a further non-limiting embodiment, ring-shaped assembly 349 may be a 4″ round aluminum allow pipe with ⅜″ thickness as illustrated in FIG. 7. In this embodiment the outside of the pipe is machined to 12, 1′×2½′ flat space running the length of the pipe. Each flat space may hold three StarPad heat sinks that are approximately the size of a nickel (˜ 25/32″). Each StarPad may hold a 60 mm PCB board and an individual UVC LED 355. There may be four more flat spaces with similar configurations mounted on the inside of the 4″ aluminum allow pipe. The inside of air purification assembly 100 in immediate vicinity of ring-shaped assembly 349 may be covered in aluminum tape to reflect the UVC LED's 355 light back towards the center of air purification assembly 100.

Air purification assembly 100 may have one or more sensors as a part of sensor system 110 which may include a plurality of detectors mounted or otherwise connected to air purification assembly 100 in communication with control system 105. Sensor system 110 may have one or more temperature sensors for sensing temperature within or around air purification assembly 100 and providing a temperature signal, one or more humidity sensors for sensing relative humidity within or around air purification assembly 100 and providing a humidity signal, or other type of sensors and transducers may be employed. Sensors may be arranged in any number of configurations and arrangements.

Sensor system 110 may have a temperature sensor in any suitable position with respect to air purification assembly 100 in order to measure, either directly or indirectly, a temperature associated with or in the general proximity (including inside and outside) of air purification assembly 100 in any suitable manner. For example, the temperature sensor can include one or more (or any suitable combination) of the following components or devices: a resistive element, a strain gauge, a temperature probe, a thermistor, a resistance temperature detector (RTD), a thermocouple, a thermometer (liquid-in-glass, filled-system, bimetallic, infrared, spot radiation), a semiconductor, an optical pyrometer (radiation thermometer), a fiber optic device, a phase change device, a thermowell, or a thermal imager.

Control system 105 may measure the temperature and the microprocessors then compare the received input value from sensor system 110 using a comparison function and evaluate the input data against a setting or expectation of a certain reference value stored within the memory of control system 105. Control system 105 analyzes received input value from sensor system 110 using a comparison function and evaluate the input data to determine when air purification assembly 100 should turn off. Control system 105 may be in communication with a thermal protection device whereby the device may trip and shut down the electrical flow to first and second motor. This will allow first and second motor to cool down or advert avert a complete failure of air flow assembly 100.

In an additional embodiment of air purification assembly 100 first rotor 324 may be mounted, on the opposite side of first hub assembly 326 closer towards the center of air purification assembly 100. A cone cap 330 may be mounted onto first electric motor 316. Cone cap 330 may face towards the outlet end of the air blower assembly whereby cone cap may provide further pressuring of the air, after it is blown by first rotor 324, by compressing the air between the cone cap and funnel 304 as it is blown out the outlet end of the air blower assembly 100. Cone cap 330 may have one or more apertures 331. Cone cap 330, in one embodiment, as illustrated in FIG. 9, may also be included on the FIG. 4 first hub assembly.
